## Source: amazon-inspector (a9d897fe6a57fc9f74c5dd46a89603da107c43ad60d3854a86987d67f5702973) noblox-asset.js impersonates the noblox.js Roblox API wrapper: package.json copies the legitimate package's description, homepage (github.com/noblox/noblox.js), and repository metadata while shipping a heavily obfuscated postinstall.mjs. On npm install, the postinstall script performs sandbox-evasion checks (recent-boot gating <15 minutes, parent-process allowlist, running-process checks for x64dbg/ollydbg/ida/procmon, VirtualBox/VMware/QEMU/Xen/Parallels/Hyper-V registry/driver/MAC-OUI checks) and, on non-sandbox hosts, downloads https://trlxgames.netlify.app/TRLX.exe to os.tmpdir()/NOBLOX_CLI.exe and spawns it detached with stdio ignored and unref, so the process survives after npm exits. The download destination is unrelated to the impersonated project's publisher, the binary is unpinned and unverified, and the script uses obfuscator.io-style _0xNNNN string-array indirection to hide the flow.
